All the Cinque Terre towns have their own train station. Almost all the trains from La Spezia stop in Levanto. Check your train schedule carefully-some trains that stop in La Spezia, also stop in Levanto, so you do not need to change in La Spezia.
PAR is an acronym for parabolic aluminized reflector. A PAR lamp, which may utilize either an incandescent filament, a halogen filament tube or a HID arc tube, is a precision pressed-glass reflector lamp. PAR lamps rely on both the internal reflector and prisms in the lens for control of the light beam.
The diameter for light bulb shape is measured at the point of maximum size. Examples are: T12 is 12 eights of on inch or 12/8 = 1.5 inches in diameter, PAR20 is 20 eighths of an inch in diameter or 2.5 inches, MR16 is 16 eighths = 16/8 = two inches in diameter.
